A networked lighting system is provided which stores, e.g. in a lighting controller node, lighting control data such as scenes or rules based on receiving such data from an application running on a first computer device. An identification of the application which lighting control data was received from is stored alongside this data. When an input is received by (a node in) the networked lighting system from an application running on a second computer device indicating that the lighting control data is to be edited, an application call is executed such that the application the lighting control data was received from is run on this second computer device.
